Ocean Lava Mumbles Triathlon

The Ocean Lava Mumbles Triathlon takes place in South Wales, offering participants a multi-sport experience along the coast. The event features two distinct distances, providing options for different experience levels. The course includes a sea swim in Mumbles Bay, followed by a bike leg on the Gower Peninsula and a run along the seafront.

Participants can choose between two main categories:

  • Olympic Distance: Consists of a 1500m swim (2 laps), a 42km bike course (1 lap), and a 10k run (2 laps).
  • Sprint Distance: Consists of a 750m swim (1 lap), a 32km bike course (1 lap), and a 5k run (1 lap).

The event serves as an Ocean Lava Qualifier. The bike leg is characterized by hilly terrain around the Gower Peninsula, while the running stage is designed as a flat and fast course across the seafront. Various accommodation options are available in the local area, including hotels and guest houses in Mumbles and the nearby Swansea City Centre.
